So it is quite an accomplishment to have been rewarded for his efforts over the past 25 years by winning the Courier's Front Garden of the Year competition.
Warwick's beautifully-kept lawn, colourful floral displays and impressive homemade hanging baskets encouraged more than 280 readers to vote his garden as Garstang's best.
And Warwick, despite being a very modest gardener, says he is very pleased and proud to have earned the title.
He said: "I never thought I would win - I just didn't think my garden was good enough! But it's amazing that I got so many votes. All the neighbours say the garden's lovely."
Warwick and his wife Marian designed their home on Larch Grove and even helped to build it. Once it was completed in August 1983, they began to create their garden, but first they had to level the ground, grow the lawn and concrete the drive. The result was a major transformation.
Warwick said: "We created the beds and things afterwards. My father was a market gardener and I was always keen on keeping the garden nice, but hadn't done a lot before. I got more interested while we were creating the garden and it's gradually built up."
Warwick used to be an HGV driver, and he found it relaxing to come home and work in the garden. He was often away for three or four days and when he got home, he liked to unwind with a bit of green-fingered toil.
Last year, Warwick and Marian decided to give the garden a make-over, with a new block-paved driveway and a lovely water feature. It was the first time they had changed the garden since they moved in.
Warwick said: "We designed the lawn a little bit differently, with curvy edges, and the new drive actually made the garden look a lot nicer."
There is no genius to Warwick's gardening talent - it is all down to trial and error and a lot of hard work. This year he decided to try some cosmos in the front garden, but next year he plans to try the dwarf version!
"They just grew much bigger than I expected," he said. "I like to try new things and see how they turn out, and if they don't turn out well, they don't come again!
"I tried blue agapanthus this year, which have worked nicely, so next year I hope to try some white ones.
"I have so many annuals, and so many bedding plants, and try to make sure there's colour all year round, which takes some planning. I grow all my own bedding plants and I make my own hanging baskets."
Warwick often visits flower shows for inspiration. His favourite flowers are busy lizzies, fuschias and roses. He mows the lawn at least twice a week, keeps on top of the weeds daily and digs round the borders to keep them looking clean and tidy.
The new water feature is perhaps the most innovative addition to the front garden - it is placed within a rockery which disguises an ugly manhole.
Warwick has particularly enjoyed watching his four grandchildren, Lucy, eight, Sam, six, Emma, four, and Katie, three, play in the garden and is pleased to have passed some of his gardening talents on to them.
He said: "I like to encourage them in the garden. Sam's dad is a farmer and he loves helping me, especially cutting round the lawn and planting things. He's very keen.
"Lucy loves helping with the plants. It's nice to see them in the garden and hopefully they will carry on my tradition!
"Quite a few people have said how well I had done to be nominated and everybody who walks up here has admired it. I get a lot of satisfaction out of gardening and after winning this competition it will be a challenge to keep it looking nice."
